SUMMARY
The Law of Constant Composition asserts that a pure chemical compound is always composed of the same elements in a fixed mass ratio. The discussion highlights confusion regarding the term "same elements," using ethanol as an example, which consists of hydrogen, carbon, and oxygen. It emphasizes that while different compounds can share the same elemental composition, they are distinct entities. The participants question the relevance of teaching this law, suggesting it has become trivial and outdated in light of modern molecular understanding.
